In this study, we first examined how people have coping strategies for social injustice and secondly analyzed the effectiveness of these strategies. We administered two questionnaire surveys. We found four types of coping strategies for social injustice: 1. need for coping by anyone, 2. need for coping by a party, 3. behavioral coping by oneself, 4. emotional coping by oneself. We also determined that there were few differences in effectiveness between the four strategy types.
